' Application filed November 14, 1883. (No model.)

To (ZZZ whom it may. concern. have an adjustable bearer, t, to rest agains Be it known that I, "EifgIIRAIM Oath, of the pattern 9, to gage the belts to the spokes Owensborough, in the county of Daviess and the belts being set by an adjusting-pulley, "a State of Kentucky, have invented a new and behind them and a little above the spokes, s 5 Improved Sand-Belt Attachment for Spokethat the belts will bear againstthe spokes whei Lathes, of which the following is a full, clear, the bearers i touch the pattern. and exact description. The pulleys a are mounted on adjustabh My invention consists of sand-belts con supports 1), attached to the bars 9, so that the trived with the cutter-head carriage, for folmay be shifted up from time to time, accord 1o lowing the cutter-heads along the spokes to ing to the tension it is desired to apply to th( smooth the same automatically after the c'utbelts.

This bar is fitted to its centers i and j adj ustabl y to enable it to be set for gaging the belts to spokes of different sizes.

The sand belt supportingbars r have a spring-hook, 7.7, to engage with a bar, Z, of the cutter-head carriage to h old them back against the sprin a, when the work and pattern holding frame f is shifted away from. the belts while removing the finished spokes and putting in the new pieces to be dressed. The pattern-mandrel in. and spoke mandrel n are geared with the pinion to which the driving-pulley q is attached by their pinions 9'), respectively.

The spoke-ceuter and patternframe is pivoted at a a little higher up than the pivots of the sand-belt stails, which. has the effect of causing the sand-belts to bear hardest on the broad l'lat sides of the spokes and in the throat, and with less pressure on the face and along toward the tenon end of the spokes.

I propose to attach si mi lar sand-belt devices to machines for turning other articles beside spokes, and whether of wood or metal, and to lathcs of other forms. The a iparatus can be applied to machines already in use as well as new ones.

Having thus fully described my invention, I claim as new and desire to secure by Letters latent- 1 The combination, with the cutter-head carriage, of the sand-belt appliance provided with one of more polishing or smoothing belts with their polishing-surfaccs presented at right angles to the length of the article held and being turned by the cutter-head, and means to adapt the said bcltorbelts to follow the cutterhead along the said article, substantially as and for the purpose set forth.

2. The combination, with the cutter-head carriage, of a sand-belt appliance having one or more polishing or smoothing belts which follow the cutter-head along the article being turned, said appliance having beveled projections which engage with beveled detaching-gnards upon the lathe-beam, whereby said appliance is automatically disengaged at intervals from the article being turned, substantially as set forth.

2;. The combination, with the cutter-head carriage, of a sand-belt appliance having one or more polishing or smoothing belts which follow the cutte1.'-head along the work, said appliance having beveled projections which engage with beveled detaching-guards upon the lathe-beam, and the spring acting upon said appliance to return it to its work after having been disengaged by said guards and projections, substantially as and for the purpose set forth.

4.. The sand-belts arranged on the drivingpulleys suspended from the cutter-head car- .riage by hangers, and on idle-pulleys supported upon bars, tlso suspended fromthe cutterhead carriage, and having bearers acting upon the pattern, said cutter-head carriage being connected to the said; bars by a spring, in combii ation with the frame having the pattern and work centers, substantially as and for the purpose set forth? 5. -.l.he sand-belts", with their pulley-supporting bars and hangers suspended fromthe cutter-head carriage, said bars having bearers acting upon the pattern, and belt-adjusting pulleys, in combination with the cutter-head carriage, and the frame having the pattern and the work centers, substantially as and for the purpose set forth.

6. The angular revolving pattern -bar, in combination with the sand-belts with their pulley-supportingbars, and hangers suspended from the cutter-head carriage, said bars being connected to said carriage by springs, and the frame having the pattern and work centers gearing with the aforesaid pattern-bar, substantially as and for the purpose set forth.

7. The combination, with the cutter-head, of a sand-beltappliance having one or more smoothing or polishing belts, and the bar acting upon said belt or belts at certain intervals, whereby the W OI'l willbe exposed to an an equal pressure at ('liti'erent times, substantially as and for the purpose set forth.

Q. The pattern-framehavi'ngits pattern-center'stock' provided with an arm, in combination with the'sand-bclt appliance suspended from the cutter-head carriage, and means to shift back the sand-belt appliance, said appliance being retained after shifting back by said arm, substantially as and for the purpose set forth.

9. The patternframe having the beveled detaching-guards, apd its pattern-center stock provided with an. arm, in 'eombination with the sand-belt appliai'lce suspended from the cutter-head carriage, said appliance having beveled projections to engage with said guards, and means to shift back said appliance, substantially as and for the purpose set forth.

10. The sand-belt appliance suspended from the cutter-head. carriage, and having a spring connecting with a bar of said carriage, in com bination with line .p. ttcrn-frame, with its pattern-center sto *k pr vided with an arm, and means to shift Tsai-l sa out of the'way,.said spring returning said applizince to its normal position after disengagement from said arm, substantially as and for the purpose set forth.
